The NO-INTRO Software Image Collection (2013-06-14 Version).
What is No-Intro?
No-Intro is a group created to preserve clean dumps and fix any ROM dumps that have been altered through intros, trainers, hacks, etc. as well as creating a complete list of all dumped games that were ever released. It gives the pal,japanese,and american variton of the roms. No bad dumps,no betas,no over dumps,no hacks,no homebrew.
What "No-Intro" does is fill some .dat files, to be used with ROM-Managers, with information about the known ROMS released. Often there are more versions of the same ROM dump, but most of them are garbage, some examples may include: bad dumps, hacks, fakes, overdumps, underdumps, and so on. "No-Intro" lists only the best available ROM; it must be a full dump with no faults and no changes to the file, basically just the ROMS that are the closest as possible to the original licensed cartridges.
